Step 1: Combine Dry Ingredients
In a mason jar, a sealable container, or a bowl, add the dry ingredients: rolled oats, chia seeds, shredded coconut, and the pinch of salt. Give them a quick stir with a spoon or fork to ensure they are evenly distributed. This prevents clumps of chia seeds from forming.

Step 2: Add Wet Ingredients
Pour the coconut milk, maple syrup, and vanilla extract into the jar over the dry ingredients.

Step 3: Mix Thoroughly
This is the most crucial step. Stir everything together very well until completely combined. Make sure to scrape the bottom and sides of the jar to ensure there are no dry pockets of oats. The mixture should be smooth and liquidy. It will thicken significantly as it chills.

Step 4: Fold in the Mango
Gently fold in your ½ cup of diced mango. By mixing it in now, the mango flavor will infuse the entire jar of oats overnight.

Step 5: Seal and Chill
Seal the jar or container with a lid and place it in the refrigerator. Let it chill for a minimum of 4 hours, but for the best texture and flavor, let it rest overnight (around 8 hours). During this time, the oats and chia seeds will absorb the liquid, soften, and create a thick, creamy, pudding-like consistency.

Step 6: Serve and Garnish
The next morning, give the oats a good stir. If they are too thick for your liking, you can add a splash more coconut milk to loosen them up. Top with your extra diced mango, a sprinkle of shredded coconut, and any other desired toppings. Enjoy chilled!
